Robert James “Bobby” Fischer, born March 9, 1943, was the strongest American Grandmaster ever. Many consider him the greatest chess playerof all time – and they are right.

In 1972, he captured the World Chess Championship from Boris Spassky of the USSR in a match held in Reykjavík, Iceland.

As we know, in the opening we need to castle. Sometimes, even strong players try to do something else and delay castling. This is a very dangerous strategy and, in most cases, should be punished by the opponent.
